Samsung Private Share

Why trust a stranger with your private files when you can control exactly who sees them and for how long?

Samsung Private Share transforms file sharing from a security gamble into a precise, user-controlled operation. Instead of sending sensitive documents, photos, or videos through unencrypted messaging apps that keep copies forever, you gain military-grade protection with blockchain-anchored access control. Every transfer is encrypted end-to-end, and you set the rules—expiration timers, screenshot blocks, and revocable access. No more worrying about accidental leaks or forgotten shared links.

Core file control mechanics

The app operates on a simple but powerful principle: you own the key, and only you decide who holds it. When you share a file, Private Share generates a unique, one-time access token. The recipient must authenticate through their Samsung account to decrypt and view the content. You can set the token to expire after a single view, after a specific time window (from 5 minutes to 7 days), or revoke it manually at any moment. The recipient cannot forward, screenshot, or save the file unless you explicitly permit it. Every access attempt—successful or denied—is logged in an immutable audit trail.

Key advantages at a glance

• Zero-knowledge encryption architecture – Files are encrypted on your device before upload. Even Samsung cannot decrypt or view your content. The decryption key exists only on your device and the intended recipient’s authenticated device.
• Granular access expiration controls – Choose between time-based expiry (minutes to days), view-count limits (one-time or multiple), or manual revocation. The file automatically self-destructs from the recipient’s device when conditions are met.
• Screenshot and forwarding prevention – The app blocks screen capture attempts and disables the share sheet during file viewing. Recipients cannot re-share, save locally, or duplicate the content without your explicit permission.
• Blockchain-anchored audit trail – Every share action, access attempt, and revocation is recorded on a tamper-proof ledger. You can verify exactly when, where, and on which device your file was accessed.
• Seamless Samsung ecosystem integration – Works natively with Samsung Files, Gallery, and My Files. No third-party accounts or additional apps required. Share directly from any file manager with one tap.
